4 Claims. c1. -241 This invention relates in general to floor-cloths and has specific reference to an improved floor-cloth adapted on the one hand to be easily attached to a cleaning tool, for example a deck swilling brush, a squeegee or any other brush of this character, so as to be easily detachable therefrom, for example when it becomesnecessary to rinse or wring the floor-cloth, and on the other hand to be re-fitted with the same facility on the brush for performing the cleaning work contemplated, the, fastenin-g device being so designed that it will not interfere with the rinsing and wringing of the floor-cloth when the latter is removed from the brush.

Patented Feb. 7, 1961 portion has an elongated shape was to extend along a substantial length of the aforesaid marginal portion of the floor-cloth whereby the binding action'will be effective on-a'considerable area and during the hot moulding step the plastic material will penetrate through thev yarn of fibre interstices of the cloth to constitute an insepara- 1 ble bond. Under these'conditions the fastening member cannot be torn'away from the floor cloth. f j

According-to a'particularly advantageous form of embodiment of this invention the-fastening'member has the general shape of a plate formed with a cavity correspondingto the -ring aperture, and with other weight-reducing recesses at those places where the removaLof'material is not likely to interfere with the strength of the device. Around the ring aperture the ring arms may "comprise'on u either side of the plate a projecting rib whereby the outer periphery of the ring portion 1 Another object of this invention consists in providing 1 a floor-clothhaving a fasteningrdevice securedpermanently" to oneof its marginal portions and adapted -to fit instantaneously on brushes of different types and sizes without appreciably increasing the sale price of the floorcloth, this fastening device being applicable, if desired, to a floor-cloth of conventional type.

Finally, this invention is also concerned with a floorcloth of the type broadly described hereinabove wherein the fastening device may last at least as long as the floorcloth itself while remaining constantly safely attached thereto.

The devices proposed up to now in this field did not meet all the requirements set forth hereinabove.

According to this invention, a fastening device for securing a floor-cloth on a brush or the like may be manufactured economically by forming this fastening device from each other whereby during this opening movement' the two edges of the slit move in a direction at substantially right angles to the main plane of the ring. 'Thus, the ring may be either fitted on a stick of a floor brush or deck swil-ling brush or squeegee, in close vicinity of the' brush portion thereof, without threading this ring throughout the stick length, or removed therefrom with the same facility by simply pulling on the floor-cloth;

, It will be noted that the moulding of the fasteningdevice and its fixation on the floor-cloth may be -effected in a single injection-moulding'operationby using a suitable plastic materialand a conventional press,

A complementary'feature of, this invention is that the v base portion by which: thef fastening member is secured I on the clothis moulded around the marginalportion or the floor-cloth which is thus embedded in the plastic inner cylindrical surface of the ring will be longer than the thickness of the plate, so that this ring will adhere with amaximum surface on the stick of the-floor-brushor squeegee. Y a s y,

The binding base portionemaybe. connected to the by a pair ofradially extending oblique arms. i I In order to afford a clearer understanding of this in- .vention and of the manner inwhich .thelsame' maybe carried out in the practice, reference;v will now be made to, the attached drawing forming part of -this specification nd, lu t t n d t l y by way o pl a typical form of embodiment of this invention. In the drawing: 1

Figure l-is a front view showing the marginal portion of the floor-cloth with the fastening device of this invention secured thereon, the ring portion being clearly visible in the upper portion of the figure;

Figure 2 is a section taken upon the line 11-11 of Fig. l; and

Figure 3 is a side view showing the ring in the open position when fitting the device on a brush stick or removing same therefrom.

In the form of embodiment illustrated in the drawing, the floor-cloth of any conventional type is designated by the reference numeral 1 and the marginalportion thereof on which the device of this invention is secured is designated by the reference numeral 2.

. The fastening device consistingof resilient thermoplastic material is moulded as an integral unit and has the general form of a plate with a base portion 3 conneeted to the periphery of the ring-by arms 4, 5 extending obliquely relative to said base portion and radially relative to said ring, as shown. The ring is split radially at 6,"that 'is, ata position diametrally opposite to the base portion, the reference numerals 7, 8 designating the resulting arms formed on either side of the slit 6. These arms have a T-shapedcrossor radial section as shownin Fig. 2, the wings of the T forming on the inner aperture side of the ring a pair of annular ribs 9,' 10 projecting on either side of the plate faces, so that the inner surface of the ring extends on a'length materially greater than the plate thickness. These nibs'9, 10 reinforce the region of the device'which contacts the stick of, the floor brushv I ments of the-arms 7, 8 which arenecessary for fitting the device on the stick andremoving same therefrom. J"

material inside this base, portion and forms a'n integralv part ofthe' fastening member. I lreferabIyQ-thebaSe -As the injection'step is carried out on the edge of the i floor-cloth the thermoplastic material is moulded around the cloth-edge and on itstwo sides, thus forming a coating i 111' and-:thus this material will penetrate deeply into the interstices between the yarns or fibres of the cloth portion located within the coating'j'll and this portion will be 1 safelyembedded in and welded-to the plastic material. Thislcoating' '11 maybe non-continuous and "cloth per,

tions 12 of any suitable contour left in their bare condition are shown to this end in Fig. 1.

To open the ring, the operator simply moves the arms 7, =8 away from each'other' in opposite directions parallel "to thering axis as shown in Fig. 3, each arm being sub jected in this case to .a resilient torsional movement around the base of said ring When the'arrns7, 8 are released, the upper ends thereof are" caused by the inherent resiliency of thelmaterial'to resume their initial position in which they register with *each' other, and the ring will remain secured on the stick without any risk of accidental removal or loosening. In fact,-a tractive effort transmitted: from the stick to the floor-cloth through the intermediary of this ring will exert a moment substantially co-pl'anar with'the ring and the substantial width of the arms 7, .8 in this plane will prevent these arms from divaricating to an extent sufficient to separate the device from the stick. Consequently, the ring cannot open itself due to the sole actionof the floor brush or squeegee on which it is fitted, irrespective of the movements accomplished by this stick.

Of course, various modifications as to the shape, proportions and material used for the practical embodiment of this device may be contemplated without departing however from the basic principle and features characterizing this invention as set forth in .the appended claims I claim:

I 2. A floor-cloth as claimed in claim 1, in which said f-as't'enin'g'nier'nber hasthe "general shape of a plate and said base po'rtio'n'ha's openings into which extendthr'eads of said floorrcloth thereby strengthening the connection of said floor-cloth .td-said' fastening member.
